Houston Texans offensive line takes major hits

It has been a rough start to rookie Nick Martin's NFL career. The regular season has yet to begin and the Houston Texans’ center is ruled out for the rest of the year with season-ending ankle surgery.

He had previously missed parts of training camp because of back issues.

The offensive line took another blow when NFL Insider Ian Rapoport reported that veteran Duane Brown won't be ready for the season opener as he's still recovering from a torn quad he suffered last season.
